133643 divided by 53 
The aim is to understand the frequency of 53 in 133643.

Moving on to step 1:
The number 53 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 53

Step 2:
The number 53 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 53

Advancing to step 3:
133 divided by 53 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 27 after subtracting 106 from 133.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 53

Moving on to step 4:
53 goes into 276 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 265 from 276 leaves us with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 53

Moving on to step 5:
53 can be fit into 114 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
Deduct 106 from 114 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 53

Advancing to step 6:
53 goes into 83 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 2521.0
If we take 53 away from 83, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
53 goes into 300 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2521.5
If we take 265 away from 300, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 53 fits into 350 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 2521.56
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 53 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2521.566
Subtracting 318 from 320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 2521.566, with a leftover of 0.0002.
